What's to know about Devic's disease? NMO spectrum disorder is a term used for patients who experience only relapsing optic neuritis or relapsing myelitis (but not both). In most cases, just the optic nerve and spinal cord of patients with NMO are affected. In very rare cases parts of the brain may also be affected.

Chapter 4 - Extraocular movement Chapter 4 - Extraocular movement. Eye movements are controlled by muscles innervated by cranial nerves III, IV and VI. In this chapter, the testing of these cranial nerves will be discussed. The most common symptom of damage to these nerves is double vision.

Overview of the Cranial Nerves Some cranial nerve disorders interfere with eye movement. 1  Eye movement is controlled by 3 pairs of muscles. These muscles move the eye up and down, right and left, and diagonally. The muscles are controlled by the following cranial nerves: 2  3rd cranial nerve. 3  4th cranial nerve. 4  6th cranial nerve.

The Extraocular Muscles When the trochlear nerve (cranial nerve IV) is damaged, a palsy of the superior oblique muscle may occur. Typically, this will resut in an excyclotorsion (outward rotation), along with a lesser hypertropia and esotropia (upward and inward movement) of the affected eye.hen the abducens nerve (cranial nerve VI) is damaged, a palsy of the lateral rectus (LR) muscle may occur, resulting in an esotropia of the affected eye. That eye generally will not be able to look outward past the midline, and it will be somewhat turned inward when the other eye is fixating straight ahead.

Optic Neuritis The optic nerve carries visual information from your eye to your brain. Optic neuritis (ON) is when your optic nerve becomes inflamed. ON can flare up suddenly from an infection or nerve disease. The inflammation usually causes temporary vision loss that typically happens in only one eye. Those with ON sometimes experience pain.

Neuromyelitis optica (Redirected from Devic's disease). Neuromyelitis optica (NMO), also known as Devic's disease or Devic's syndrome, is a heterogeneous condition consisting of the simultaneous inflammation and demyelination of the optic nerve (optic neuritis) and the spinal cord (myelitis). It can be monophasic or recurrent.evic's disease is more common in Asians than Caucasians. In fact, Asian optic-spinal MS (which constitutes 30% of the cases of MS in Japan) has been suggested to be identical to Devic's disease (differences between optic-spinal and classic MS in Japanese patients).

Vision problems Vision problems. Visual symptoms which are common in MS include optic neuritis, uncontrolled eye movements (nystagmus), blurred vision, and double vision (diplopia). Although common, these symptoms seldom result in permanent blindness. What is optic neuritis and how is it treated? Optic neuritis is an inflammation of the optic nerve. Nerve damage caused by optic neuritis can result in changes in color vision (eg. color red becomes dull), blurring or graying of vision, appearance of a dark spot (scotoma) in the central visual field, or temporary blindness (typically in only one eye).

Eye movement (sensory) Eye movement of inferior oblique muscle, superior view. Anterior view. The muscles are supplied by the oculomotor nerve, with the exception of the superior oblique, which is supplied by the trochlear nerve, and the lateral rectus, supplied by the abducens nerve. special type of eye movement, rapid eye movement, occurs during REM sleep. The eyes are the visual organs of the human body, and move using a system of six muscles. The retina, a specialised type of tissue containing photoreceptors, senses light.

Muscles, Nerves, and Blood Vessels in the Human Eye Ocular nerves allow you to interpret what you see and blood vessels keep your eyes oxygenated. Six muscles, collectively called the extraocular muscles, move the eyeball. A seventh muscle moves the eyelid and is also found in the orbit.

- Damage to the nerves in the feet or legs is the most common nerve damage from diabetes. However, diabetes can also affect the nerves to the eye. Having high blood glucose from diabetes causes decreased blood supply to the optic nerve. You may suddenly have double vision, drooping of your eyelid, or pain over your eye.

- Although Graves’ Ophthalmopathy is caused by a hyperactive thyroid, the hormones that affect the eyes are not the same ones that cause reactions in other parts of the body. In roughly 10% of cases, people with Graves’ Ophthalmopathy do not actually have Graves’ disease. In extreme cases of Graves’ Ophthalmopathy, swollen eye muscles may put extreme pressure on the optic nerve, leading to double vision, or vision loss.

Neuromyelitis Optica Neuromyelitis optica (NMO) is an uncommon disease syndrome of the central nervous system (CNS) that affects the optic nerves and spinal cord.ecent discoveries, however, suggest it is a separate disease. NMO is different from MS in the severity of its attacks and its tendency to solely strike the optic nerves and spinal cord at the beginning of the disease.

- The leading symptom of patients with superior oblique myokymia (SOM) [17] is recurrent short attacks of monocular “jumping images” or blurred vision (oscillopsia) [18••]. Patients also report transient vertical and/or torsional diplopia. Attacks can occur many times a day and last over a range of seconds.

- Pressure on parts of the brain or cranial nerves (which connect the brain directly to various parts of the head, neck, and trunk) can affect eye movements. People may have double vision or be unable to move their eyes in certain directions, or the eyes may move involuntarily in certain ways (called nystagmus).

What Is Microvascular Cranial Nerve Palsy? Microvascular Cranial Nerve Palsy (MCNP) is when blood flow to certain nerves in your head (called cranial nerves) is blocked. As a result, you may not be able to move your eye a certain way. Also, you will have double vision. Double vision is when you see two of a single image—either side by side, or one above the other. Your brain sends signals to your eye muscles through 3 nerves. If blood flow to one of these nerves is reduced, certain muscles cannot move the eye.

- There are actually 12 cranial nerves; three of them stimulate the eye muscles, while three others affect the eye in other ways. “LR 6” is the lateral rectus muscle stimulated by cranial nerve 6. “SO 4” is the superior oblique muscle stimulated by cranial nerve 4.The “3” is for cranial nerve 3 which stimulates, innervates, the remaining eye muscles.Cranial nerve 2 is also called the optic nerve.here are actually 12 cranial nerves; three of them stimulate the eye muscles, while three others affect the eye in other ways. “LR 6” is the lateral rectus muscle stimulated by cranial nerve 6. “SO 4” is the superior oblique muscle stimulated by cranial nerve 4.

- It affects the third cranial (oculomotor) nerve. This is one of the cranial nerves that control eye movement. Local tumors or swelling can press on and damage the nerve. Causes may include: 1  Brain aneurysms. 2  Infections. 3  Abnormal blood vessels (vascular malformations).

- Optic nerve swelling may cause eye pain. Steroids are often used to treat optic nerve swelling through IV treatment. Multiple sclerosis can cause optic nerve swelling. Ocular neuritis can occur when the optic nerve, the nerve which transmits the signals of the eye to the brain, becomes inflamed.Optic neuritis can result in vision loss that runs the gamut from mild to severe. Symptoms of sinusitis include facial pain.Hypothyroidism is a potential cause of optic nerve swelling.cular neuritis can occur when the optic nerve, the nerve which transmits the signals of the eye to the brain, becomes inflamed.

What is the function of trochlear nerve? Without the use of the nerve, the superior oblique eye muscle will no longer function properly. The muscle, not the trochlear nerve, is what physically moves the eyeball. Double vision, otherwise known as diplopia, results from problems with either the muscle or the nerve.t serves the superior oblique eye muscle and connects to the annular tendon. As a result, it processes brain signals to move the eyes up and down, and also outwards. Whether due to a head injury or a complication of surgery, damage to this nerve will compromise some ability to use the superior oblique eye muscle.

Neuromyelitis Optica The syndrome can also damage nerve fibers and leave areas of broken-down tissue. In the disease process of NMO, for reasons that aren’t yet clear, immune system cells and antibodies attack and destroy myelin cells in the optic nerves and the spinal cord.
